A winter wetsuit?! I'm not sure where you're diving but if it's anywhere around the UK, you had better get a winter drysuit!
Man speaks the truth!
4-4.5c inland and 5.5 on the coast at the moment!
I was in the drysuit last week in egypt!! Might be ok in the water in a wetsuit but out quickly becomes an issue.
UK water never gets warm enough for a wetty!
If you're looking at the very budget end I can recommend Tesco value bin bags
